Lyophilized from sterile PBS, pH 7.4.Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA. |
| Bio-activity : |
1. Measured by its binding ability in a functional ELISA. Immobilized human CD2-His (Cat:10982-H08H) at 10 μg/ml (100 μl/well) can bind human CD58-Fc, The EC50 of human CD58-Fc is 0.04-0.1 μg/ml.2. Measured by its binding ability in a functional ELISA. Immobilized Cynomolgus CD2-His (Cat:90300-C08H) at 10 μg/ml (100 μl/well) can bind human CD58-Fc, The EC50 of human CD58-Fc is 0.04-0.10 μg/ml. |
| Molecular Mass : |
The recombinant human CD58/Fc is a disulfide-linked homodimer. The reduced monomer comprises 428 amino acids and has a predicted molecular mass of 48.5 kDa. The apparent molecular mass of the protein is approximately 68 kDa in SDS-PAGE under reducing conditions. |

| Storage : |
Samples are stable for up to twelve months from date of receipt at -20°C to -80°C
Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. |
| Reconstitution : |
It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents. |
